Title: An improved process for roasting sulphide ores
Inventor: QUINTIN ALBERT ANDRE JOSEPH
IPC: C22B1/10
Filed: 1953-08-21
Abstract: <PICT:0739213/III/1> In a fluidizing process for roasting sulphide ores, particularly zinc blende, the main oxidizing current of air is injected so as to cause three distinct zones of material to be formed-an upper zone of normal fluidized conditions, an intermediate zone of intense turbulence and a lower zone of no fluidization, from which the completely roasted ore is withdrawn.  In Fig. 2 the ore is fed through a pipe 15 and the principal air supply is admitted through nozzle 4 from chambers 3 in streamlined hollow bars 2 which restrict the cross-section of the reactor whereby a zone of intense turbulence is produced at this level, above which is a zone of normal fluidization extending up to level 17.  To complete the reaction, a secondary air supply insufficient to agitate the ore is admitted through nozzles 6 from chamber 5 in the lower parts of the bars 2, and the unfluidized bed 7 is traversed by a small tertiary air supply admitted at 9.  The roasted ore is withdrawn by a conveyer 10.

Title: Improvements in or relating to machines for stencil printing on rotating articles
IPC: B41F15/08
Filed: 1955-08-11
Abstract: 777,193. Stencil-printing on bottles &c. SOLAR ENGINEERING & EQUIPMENT CO. Aug. 11, 1955, No. 23174/55. Class 100(2) In a machine for stencilling decorations on to a rotating bottle 10 or other article, registration means to stop rotation of the article in a required position by engagement with an index 25, Fig. 6, on the article comprises a member 24 pivoted about an axis 40 parallel to that of the article, the member having a nose 52 engageable with the article and a tooth 50 engageable with the index, the nose and tooth being so disposed relative to the axis 40 that engagement of the tooth with the index presses the nose against the side of the article. The arrangement enables the member 24 to ride on the side of the article even when the latter is not truly cylindrical, causes the tooth, once having contacted the index, to move further into engagement therewith, but transfers the resulting inward thrust on the side of the article, which might fracture it if applied by the tooth, to the nose which spreads it over a wider area; if the nose is further from the axis of the pivotal member than the egective distance B of the tooth therefrom, the total inward thrust C is reduced. As shown, the tooth 50, of tool steel, is clamped into a bore in the member 24 by a set screw 51, Fig. 1, the axis 40 is a stub shaft projecting from an axially adjustable block 30, bolted to a carriage 31 mounted on a dove-tail slide for horizontal adjustment by a screw 37; the slide is on a plate 34 vertically adjustable on an arm 26 pivoted to the machine frame at 27 and normally held in registration position by a link 28, but retractable to position 29 for loading and transfer of the bottles. The member 24 is biased towards the bottle 10 by. a spring 43, Figs. 1 and 6, and is prevented from moving too far (when the arm 26 is in retracted position 29) by a stop 48 on a slotted plate 45, horizontally adjustable relative to its fixing bolts 47. The mechanism is adjusted so that if the index on the bottle 10 is a recess 25 as shown in Fig. 6, the tooth 50 rides on the bottle, whereas if the index is a lug the nose 52 rides on the bottle with the tooth sufficiently close to intercept the lug. The bottle 10 is held' by a movable holder 12 against a chuck 11 rotated for registration by a sprocket drive 15, 14, 16, from a shaft 13 geared to the machine' main shaft, and for stencil printing by a drum 18 coupled by cable 17 to the rectilinearly moving stencil frame (not shown); a twoway clutch 19 transfers the drive, making a firm connection with the drum 18 and a frictional connection with the chain wheel 16 to allow slip after the tooth 50 has engaged the index 25 and stopped the bottle.

Filed: 1947-08-21
Abstract: 637,399. Gravity-separation apparatus. NEWMAN, R. H., and HIRSHSTEIN, M. P. Aug. 21, 1947, No. 23201. Convention date March 24, 1939. [Class 111]. A waste water, grease, oil, and fats separator comprising a continuous flow container 10, Fig. 3, having a waste water outlet 12 communicating with a region 17 at the bottom of the container and disposed above the bottom to determine the inital normal waste water level 22, is provided with a grease, oil, and fats draw-off mechanism comprising a valvecontrolled draw-off port 35, Fig. 4, disposed slightly above the normal water level 22 and operated by a float-type valve mechanism serving to open the port only after an accumulation of grease, &c., within the container has lowered substantially the waste water level therein. As shown the draw-off port is formed by the horizontal open end of a stand-pipe 24 communicating with an outlet 26 from which the greasy materials flow to a tank 27, and the stand-pipe 24 forms a support for the bracket 30 of the valve mechanism, means being provided to adjust the position of the bracket on the stand-pipe. The valve-mechanism comprises a valve member 37 having a tapered surface co-operating with a similar surface on the valve seat 35, the stem 37a of the valve member being connected by levers 39, 40, fulcrummed on the bracket 30, to a member 38 adjusted to float on the surface of the waste water, the buoyancy of the float being adjustable through the screwed plug 43. A shield 45 adjustably mounted on a sleeve 46 carried by the stand-pipe 24 prevents the access of solid matter to the valve 35, 37, the shield 45 and sleeve 46 being suitably apertured to permit the flow of liquids. The outlet 12 is formed on a riser 18 extending vertically from the basin outlet passage 17 and a cover 19 may be provided together with a passageway 20 extending from the uppermost part of the inside of the basin downwardly to open into the riser 18 below the normal water level 22. Baffles 13, 14 may be provided to decrease the velocity of inflow and to create turbulence. On flushing waste liquids into the basin the liquid level therein rises above the normal level 22 so that the float keeps the valve 35, 37 closed. When flushing ceases the liquids become quiescent and the greases &c. which have separated out from the waste water depress the waste water level in the basin until the float 38 falls sufficiently to open the valve 35, 37 whereupon the grease &c. flows off through the stand-pipe 24.
